NASA Unveils Anatomy Of A Comet
Findings from the historic encounter between NASA's Stardust spacecraft and a comet will be discussed during the next Space Science Update (SSU). The SSU is 2 p.m. EDT, Thursday in the NASA Headquarters Webb Auditorium, 300 E St. SW, Washington.

The findings were made when Stardust flew within 236 kilometers (about 147 miles) of comet Wild 2 on Jan. 2, 2004. It captured the most detailed, high-resolution comet images ever seen.

SSU Participants:
  • Dr. Thomas Morgan, Stardust program scientist, NASA Office of Space Science, Washington
  • Dr. Donald Brownlee, Stardust principal investigator, University of Washington, Seattle
  • Dr. Benton Clark, Chief Scientist of Space Exploration Systems, Lockheed Martin, Denver
  • Dr. Claudia Alexander, Project Scientist, U.S. Rosetta Project, NASA's Jet Propulsion Laboratory, Pasadena, Calif.

NASA TV will carry the SSU live with two-way question-and-answer capability for reporters covering the event from participating NASA centers. NASA TV and live webcast is available on AMC-9, transponder 9C, C-Band, located at 85 degrees west longitude. The frequency is 3880.0 MHz. Polarization is vertical, and audio is monaural at 6.80 MHz.
